Application filed December 5. 1907. Serial No. 405.255-

To all whom it may concern:

Be it known that 1, WILLIAM SEIBERT, a citizen of the United States,residing at Erie, in the county of Neosho and State of Kansas, haveinvented a new and useful Rotary Engine; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention pertains to a new and useful rotary engine and theinvention in its broadest aspect aims as its primary and essentialobject to provide a device of this character by which the inlet for thesteam is controllable by a sliding valve, which is controlled by arotatable head.

The invention aims as a further object to provide a steam gate whichopens and closes, in front and the rear of the piston carried by therotatable head; this steam gate and sliding valve are simultaneouslyoperated and controllable by the rotatable head, so as the steam will beadmitted in the rear of the piston, at the time when the steam gate isnearing a closed position, in the rear of the said piston.

A further object of the invention is to provide a device of this type,having reversible means for changing the entrance of steam, whereby therotatable head is reversed in its movement, as will be clearly manifest.

This invention is provided with an exhaust port, and the inventiondirects as a further object to provide a device of this character, whichis simple and efficient in construction, as well as being inexpensive tomanufacture.

This invention comprises further objects and combinations of elementswhich will be hereinafter more fully described, shown in theaccompanying drawings, and the novel features thereof will be pointedout by the appended claims.

The features and elements and arrangement thereof, for accomplishing theobject of the invention, may be changed and varied, that is to say, in apractical application of the device, with an understanding that the.

changes and variations accruing from said application are limited to thescope of the appended claims.

To obtain a full and correct understanding of the details ofconstruction, combinations of features, elements and advantages, refer'ence is to be had to the hereinafter set forth description and theaccompanying drawings n connection therewith, wherein Figure 1 is anelevation of the improved rotary engine. Fig. 2 is a sectional View uponline 22 of Fig. 1, looking in the direction of the arrow, illustratingthe steam gate, the steam chamber, and the steam inlet and its slidingvalve. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 4 is anenlarged detail of the rotary head and its piston. Fig. 5 is aperspective view of the said rotary head and its piston. Fig. 6 is anenlarged sectional view of the piston, showing the manner of fasteningthe same to the rotary head.

Like reference characters are used for indicating similar features andelements throughout the several illustrations.

In regard to the accompanying drawings wherein similar referencecharacters indicate corresponding parts in the several illustrations, byfigures, a designates the casing of the rotary engine, which comprisestwo disk sections 1 and 2, which are centrally bored, as at 3, so aswhen placed in registration, the said bored portion will provide acylindrical space in which the rotary head 4 rotates, with which iscarried the piston 5, which piston is fastened to said rotary head bymeans of screws 6, as clearly shown in Fig. 6. This piston comprises twomembers 7 and 8, which are held together by means of the screw 9, asclearly shown in Fig. 6. These two members are provided with annularrecesses 10 and 11, upon the adjacent faces thereof, and when placed inregistration, said recesses receive and hold a suitable packing 12, asalso clearly shown in Fig. 6. The said rotary head is held in said spaceby means of the annular rib 13, which rotates in a contracted portion 14of said casing, as clearly shown in Fig. 2. Adjacent to this contractedportion 14, the said sections 1 and 2 are provided with annular recesses15, in which the packing 16 carried by the rotary head moves; thispacking is also seated in annular recesses formed in the said headadjacent to the annular rib 13, as shown clearly in Figs. 4 and 5.

At a diameter greater than the diameter of the centrally bored portionsof the sections 1 and 2, the said sections upon their adjacent faces,are provided with concentric recesses 17, which are semicircular incross section, and when the sections are placed against one another,"the. said recesses 17 form a steam chamber 18, in which the pistoncarried by the rotatable head travels, as will be clearly manifest. Thesaid sections 1. and 2 are held adjacent to one another by any suitablemeans, preferably bolts 19, as shown in the drawings. tion of the saidcasing is a casing 20, which forms a chamber 21, in which the reversiblevalve 22 is operated; this valve is movable with the shaft 23, whichreciprocates through packing boxes 24, as clearly shown in Fig. 3.Carried at each end of the shaft 23 are sliding'valves 25, which areadapted to close the exhaust ports 26 and 26, which communicate with thesaid steam chamber. Vvhen the piston is moving in the directionindicated by the arrow 27, the port 26 will act as the exhaust for thesteam, and to reverse the movement of said piston, the said shaft 23 isreciprocated, thus closing port 26 and opening port 26, which will allowthe steam to exhaust through said port 26. In changing the exhaust, thesaid valve 22 closes port 28, and opens port 29, which changes theadmission of steam upon the opposite side of the steam gate 30, whichwill reverse the movement of said piston.

The steam gate 30 is of a sliding type, and is movable within thechamber 31 provided upon the section 1 of the casing; this chamber isformed by a casing, which laterally projects from the said section 1,and is held thereto by several bolts 32, as clearly shown in Figs. 1, 2and 3. The said casing in which the steam gate operates, is providedwith a stuffing box 33, through which the rod 34 reciprocates, which rod34 is integral with the said steam gate; fixed at the end 35 of saidrod, by means of a shoulder 36 and the nut 37, is an angled portion 38of a member 39, at the inner end of which an anti-frictional roller 40is provided, which cooperates with the cam projection 41 carriedintegrally with the said rotatable head, as clearly shown in Figs. 1 and2. The journal upon which the said anti-frictional roller is mounted isslightly extended, and is guided in an elongated recess 42, formed uponthe lower portion of the chamber in which the said steam gatereciprocates, for the purpose of insuring an even movement for the steamgate, as indicated at 42 in Figs 1 and 2 of the drawings; this elongatedrecess is simply rectangular in cross section, as further shown inFig. 1. From the above description in connection with the annexeddrawings, it will be plainly seen how the said sliding gate is openedand closed, in front and rear of the said piston, as it rotates in thesteam chamber. The said cam projection operates the said gate, so as to'open the same against the tension of the spring 43, one end 44 of whichis fastened to the angled portion of the member 39, while the end 45'isfastened to the side of the casing,

Fixed upon the upper porin which the said gate operates. By the use ofthe said spring, it will be understood how the steam gate is closed,after being opened by the said cam projection. and 2 are provided withears or lugs 47, by which the entire casing formed by said sections, aresecured to any suitable support, such as for instance the framing orrunning gear of an automobile, as will be manifest. The shaft 23 isprovided with a handle or grip 48, by the use of which, the said shaftis reciprocated. I

Secured to the side, and adjacent to the upper part of the section 2, isa casing 49, forming a steam chest 50, which communicates with thechamber 21, by means of the passage 51, which is alternately opened andclosed by the sliding valve 52, which reciprocates within said steamchest, as clearly shown. This valve 52 is connected to a reciprocatoryrod 53, which moves through a stuffing box 54, and is operated by a cam55, as clearly shown. The said rod 53" is provided at its lower end withan anti-frictional roller 56, which engages said cam 55. The said rod 53moves through suitable bearings 57, be tween one of which and a shoulder58 of said rod, a spring is disposed, so as to continually hold saidanti-frictional roller 56 in contact with said cam. The said cam 55 iskeyed to The sections 1 the shaft 59, as is also the rotatable head, as

at 60 and 61, so as to cause the said head, shaft and cam to rotate asone body.

The valves 25 are mounted to reciprocate in recesses or guides 62 of thesaid casing, as clearly shown in Fig. 3. grip 48 and the valves 25 arefastened to the shaft 23 by means of nuts 63, as clearly shown in Fig.3.

From the foregoing, the essential features, elements and the operationof the device, to gether with the simplicity thereof, will be clearlyapparent. I
